MOLD FOR CEMENT POSTS.

Specification of Letters Patent.

Patented Sept. 24, 1907.

Application iiled June 14,1906. Serial Nol 321,605.

To all whom it may concern:

Be it known that I, CHARLES HUTCI-IINS, a citizen oi the United States,residing at Pataskala, in the county ot' Licking and State oi Ohio, haveinvented cert-ain new and useiul Improvements in Molds for Cement Posts,et which the following is a specification.

My invention relates te a mold tor cement posts and the like and has iorits obj ect the provision of a device et this character adapted toreceive and retain a body oi concrete er cement until the saine hardens,said mold being constructed in such manner that it may be readilystripped irom said post aiter the material has set.

A further object oi' the invention is the provision of a mold adapted toaccomplish the objects set forth in the foregoing paragraph and likewiseto form a groove or recess in the lace oi the post.

A iurther object et the invention isthe provision ei a mold constructedin such manner as to receive and retain wire engaging members until thematerial forming the post hardens or sets and also constructed in suchmanner that it may be readily stripped from the post and from said wireretaining devices after said material has hardened.

Further objects and advantages oi the invention will be set forth in thedetailed description which now iol-` lows. A 1

In the accompanying drawing: Figure 1 is a transverse vertical sectionalview ot' a cement fence post mold constructed in accordance with theinvention and illustrating said mold surrounding a cement ience post,Fig. 2 is a horizontal section upon line x a' oi Fig. 1, Fig. 3 is ahorizontal section of said cement ence post aiter the mold has beenstripped tlierel'rom and illustrating a strand ot fence wire securedthereto, Fig. 4 is a view similar' to Fig. 3, illustrating a modifiedform of wire retaining member, Fig. 5 is a view partially in sideelevation and partially in section oi the post shown in Fig. 4illustrating the mold inclosing said post, and, Fig. 6 is a view oi thepost itselt', illustrating one oi the retaining devices bent about astrand et' the tence wire.

Like numerals designate corresponding parts in all et the iigures oi thedrawing.

Relerring to the drawing and particularly to Figs. 1 and 2, the numeral5 designates a tapering metallic casing which forms the body portion ot'the mold. This casing is provided with iianges 6 which are periorated asat 7, ior the reception ot' bolts S. These bolts pass through a strip 9which is preferably formed of wood and which has a V-shaped inner face9/. The bolts serve to clamp the flanges 6 firmly against the sides ofthe strip 9.

Wire retaining pins 10 which are headed as at 11 pass throughperfor-ations 12 formed in the strip 9 and serve a purpose which will behereinafter set forth. A binding wire er rod 13 passes verticallythrough the post and is looped at its lower end 14. The upper end oithis rod or wire extends to any desired distance above the top oi thepost and is adapted to have strands oi the fence wire secured thereto.

The operation of the device is as follows: In using this cement postmold, an excavation 15 is Erst formed in the ground, which is indicatedby the numeral 1G. This excavation is then partially filled with cement,after which the mold is placed in position with its lower end restingupon the body et' cement which has been placed Ain the excavation. Therod or wire 13 is then placed vertically in the mold and pushed down tethe bottom oi the cement previously placed in the excavation and saidmold is iilled with cement through its upper end. While this cement isstill in a plastic condition, the pins 10 may be moved through theopenings 12 of the strip 9 te any desired position. After the cementhardens or sets, the bolts 8 are removed and the strip 9 is strippedfrom the pins. The V- shaped inner face of this strip leaves a V-shapedrecess 17 in the iace 0i the finished post (see Fig. 3). The bodyport-ien of the mold is then stripped from the post by slightlyseparating the flanges as illustrated in dotted lines in Fig. 2 andsliding the mold from the top ot' the post. It is apparent that thestrip 9 may be reversed to present its plane face to the post it it isnot desired to form a groove therein. When the concrete hardens, theloop 14 is firmly embedded therein,

as well as the wire 13 and the headed pins 10. The

remainder oi' the excavation is then iilled with earth. That portion otthe concrete which was placed in the excavation prior to placing themold in position forms an anchor which resists any tendency oi the postto move upwardly under the influence of frost. The strand wires ei thetence, one oi which is indicated at 18,` are then run across the face etthe post and the ends ol" the pins 10 are bent about said wires, asindicated at 19, drawing them into the V-shaped groove 17 to therebysecure any desired tension. These wires correspond in number to the pins10 and these pins may be spaced apart and of such number as to give afence oi any desired number of wires and of any desired height. A moldConstructed as herein shown and described, renders it possible to moldthe fence posts in the ground at the place Where they are to be used. Byusing a set of eight 0r ten of these molds, the operation oi setting thepests may be steadily continued.

Ii desired, the heads 11 may be omitted from the pins and the pinspassed entirely through the post and through the opposite side o themold, as is illustrated in Fig. 5. When this is done, the pins arepushed back just through the openings in the mold which are lief' movedinwardly until their ends may be bent over upon the exterior ol the postas is indicated at 2() in Fig. 4.

From the foregoing description, it will be seen that simple andefficient means are herein provided lor accomplishinzgr the objects oithe invention, but while the elements shown and described are Welladapted to serve the purposes lor which they are intended, it is t0 beunderstood that the invention is not limited to the precise constructionset forth, but includes within its purview such changes as may be madewithin the scope of the appended claims.

What I claim, is:

In a device of the character described, the combination with a flexibleand integral mold body which is open entirely filone; one side thereofand which tapers toward its upper end, et an onttnrned Iiange formedupon the niold body at each side ot its open portion, a strip having:y:1 series of centrally arranged perforations formed therethrough whichare adapted to receive fastening devices that extend troni the center etthe post to be molded, said strip entirely idling;- the space betweensaid Iianges and lieirJ," adapted to be stripped bodily from thefastening devices when nioved away from the mold, and bolts removablei'ioln the exterior of the mold which pass through both the ilanges :indthe strip.

In testimony whereof I :iITix my signature in presence ot two witnesses.
